• Visual Basic How to set a printer to be the system default printer?

  Hi all, first of all: please be pateient with me as I'm not at all an experienced VB programmer. Reading lots of articles on MSDN I learned how to use PrinterSettings and PrintDialog and control printer settings. What I didn't find, though, is a way to make one of the installed printers the system default printer using VB 2005 Express. If - for some reason - that's not possible using VB 2005 Express, there's still a 2nd option; in the forums I found a link to a technote explaining how to set the default printer using VB 6.0 / through Win32 API calls (http://support.microsoft.com/default.aspx scid=kb;en-us;266767). I'd like to avoid the hassle, but if necessary I would do it. Unfortunately, I don't know how to retrieve the CURRENT system de ...Show All

• Visual C++ Can't vcbuild a project from another directory?

  I have a solution made of multiple projects which I am trying to migrate from VS6 to VS2005. The original uses nmake and msdev, so I'm trying to replace msdev with vcbuild. I've found the following odd behavior: Let's say I have a directory tree that looks like this: ..\aa\bb\ containging project.sln and project.vcproj ..\cc\ containing my makefile Now, when I'm in \aa\bb I can type ' vcbuild project.vcbuild "Release|Win32" ' and it builds fine. However, when I'm in \cc I type ' vcbuild ..\aa\bb\project.vcbuild "Release|Win32" ' and I get a whole slew of link errors. Using the equivalent msdev commands on the .dsp file works fine. Of course, the project builds fine in the IDE too. How can I use vcbui ...Show All

• Visual Studio Express Editions Changing selected font with multiple RichTextBox controls

  I'm creating an application that creates a document using data from multiple RichTextBoxes. Some of the text that is entered will need to be formatted using formatting buttons (like the bold/italics/underline buttons in Word). The problem is, since I have multiple text boxes the program does't know which text box to apply the format to. Using Form1->ActiveControl returns the tool strip control from where the button is so that's no help. Any ideas Note: The richTextBoxes are all contained in an array of richTextBoxes i.e. private: cli::array<System::Windows::Forms::RichTextBox^>^ richTextBoxes; Thanks. Write an Event handler for all the RichTextBox controls so you know whi ...Show All

• SQL Server Dumb, but necessary, question on SSIS feature completeness

  We have never built a data warehouse. We are not even sure what the required features are to do this. Nontheless, our developers are exploring two ETL tools: SSIS and Sunopsis. They tend to like Sunopsis because it has been around a few years, has the equivalent of source-code modules (libraries) in the tool, has a highly granular security system, has 500 companies using it. and therefore must have survived several ETL projects. (We don't know if, or how many, real-world projects SSIS has been used for.). Sunopsis is Java based and uses its own authentication scheme (no support for Windows Active Directory yet. Bummer) To the best of your knowledge is SSIS, out of the box, missing any of the standard functionalites needed to populate ...Show All

• Architecture BPEL, XPDL and BPMN

  "BPEL is a standard which supports webservices and system to system applications workflow. For more of a human workflow, XPDL promoted by WFMC is the best." "BPMN is for modelling and supports both XPDL and BPEL. Simple BPEL based modelling tools for BPMS systems lacks a lot compared to BPMN based systems" Please provide me with your comments on the above statements. Also that, what standards are been followed in WF.

• Visual C# Trim file path to file name

Sounds simple, right So I take this: "C:\Program Files\Test\Test.txt" And I get this: "Test.txt" I realize that this is probably a commonly asked question, but search yielded no results. (Not to mention that the msdn website search is horrible - you can't just search in your current section instead of the whole global msdn) Use google to search MSDN, it's the only way to find anything.
